Aurelia - a can't live without component

Obviously, I've got to show wait cursors while my backend code is running. Rather than write it a bunch of times, I built the tiniest of custom elements and I use it everywhere now:

  <template>

    <i class="fa fa-circle-o-notch fa-spin fa-2x payrazr-blue"></i>

  </template>

The class named color-class is used to pick the standard color of the spinner. No javascript behind this one, just an HTML-only component using Font Awesome.
